Example violations include: the axis upon which the firing arm rotates drops during launch, the center of gravity of the unloaded device drops during a launch motion, the triggering process provides momentum to the launch, a form of potential energy (compressed or stretched elastic solids, compressed air, etc.) is used. Without a counterweight and projectile, the launch arm must not make a launch motion when released from any position before the point where the projectile is released. Allowable types of devices include, but are not limited to, counterweight and floating-arm trebuchets, subject to these rules.
What you just asked about is highly illegal in this event.
There is illegal and legal in science olympiad, there is nothing that is slightly illegal and nothing that is extremely illegal. Having a device that breaks the energy rule and having a device that shoots flames are equally illegal.
